VALVE-ATTACHING DEVICE FOR BICYCL-TIRES.

SPECIFICATION forming part of Letters Patent No. 657,060, dated August28, 1900.

Application iiled December 5, 1899. Serial No. 739,230. (No model.)

T al?, 107mm, it may concern:

Be it known that I, ROBERT J. BURNS, of Avon, in the county of Norfolkand State of Massachusetts, have invented a new and useful Improvementin Valve-Attaching Devices for Bicyele-'l`res, of which the following,taken in connection with the accompanying drawings, is a specification.

My invention relates to valve-attachin g deio vices Vfor bicycle-tires,and is especially adapted for use upon that class of tires in which thevalve and its casing are connected to the tire bymeans of a tube ofrubber cemented to the periphery of the tire and projecting therefromtoward the axis of the wheel when the tire is placed in position uponthe rim of the wheel; and it consists in certain novel features ofconstruction, arrangement, and combination of parts, which will bereadily zo understood by reference to the description of theaccompanying drawings and tothe claims hereto appended and in which myinvention is clearly pointed out.

Figure l of the drawings is a side elevation z 5 of a small section of apneumatic bicycle-tire with valve and valve-tube attached thereto andillustrating my invention. Fig. 2 is a .transverse section of the sameon line fr on Fig.l,butshowingthe valve in elevation. Fig. 5o 3A is aplan of the split clamping-sleeve. Fig.

is a sectional elevation of the same, the cut? ting plane being on liney y on Fig. 3. Fig. 5 is a plan of the binding-nut, and Fig. 6 is asection of the same. Figs. 3, 4, 5, and 6 are drawn to an enlargedscale.

In the drawings, l represents a small section of an ordinary pneumatictire having a perforation 2 formed therein, over which is cemented tosaid tire the flanged rubber tube 4o 3, in which is inserted thevalve-casin g 4, provided with suitable valve-seats and having fit-tedtherein suitable valves, which valves, valveseats, and the casing may beof any well-known construction and form no part of my present invention,and therefore need not be described in detail here. A metal sleeve 5,having an internal diameter when in its normal or uncompressed conditionsuiciently large to permit itto pass freely over the tube 3, issplitentirely through longitudinally on 5o one side, as at 0, and nearlythrough on the other side, as at '7, is slipped over said tube 3 afterthe valve-casing, with its valve, has been placed in position therein.The sleeve 5 has formed upon its inner surface the an- 55 nular bead 9,as shown in Fig. 4. Exteriorly the sleeve 5 is made slightly tapering,being largest at the end which when placed in position is farthest fromthe tire and is threaded from end to end. A ringnut 8 is fitted to 6osaid sleeve in such a manner that as it is screwed thereon from thesmallest end of said sleeve it will compress said sleeve and cause it toclamp said rubber tube 3 firmly upon the valve-casing and hold itfirlnlyin position.

Vhen the valve-casing is placed in the tube 3 in its proper position,the nut S is slipped over the tube 3 into proximity to the tire. Thesleeve is then slipped over said tube 3 into the desired position, andthen the nut 8 7o is brought into engagement with the thread on saidsleeve at its smaller end and screwed thereon toward its larger enduntil the rubber tube is firmly clamped to the valve-casing and the bead9 is pressed into the rubber 75 tube.

By the employment of this attaching device the valve-casing may bereadily removed, repaired, and replaced without detaching the anged tube3 from the tire, as has hereto- 8o fore been necessary. This is a verygreat advantage.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is

l. As a means of securing the valve-casing in a rubber air-inlet tube ofa bicycle-tire, a metal sleeve made tapering and threaded upon itsexterior and split entirely through, longitudinally, on one side, andnearly through upon the opposite side, and approxi- 9o mately fittingthe exterior of said rubber inlet-tube in its normal condition; and anut fitted to said sleeve and arranged to compress said sleeve to clampit upon said tube, and said tube to the valve-casing.

2. In combination with a pneumatic tire provided with a rubber air-inlettube, and a valve-casing inserted in said inlet-tube, the

sleeve 5 provided With the slits 6 and 7, and In testimony whereof Ihave signed my 1o annular bead f), and having a screw-thread name tothis specification, in the presence of formed upon its taperingexterior; and the two subscribing witnesses, on this 2d day of nut 8,the threaded perimeter of which is it- December, A. D. 1899.

ted to the smaller end of said sleeve, and 1 r1 adapted to compress saidsleeve as it is ROBBRl J BURNS screwed toward the larger end thereof,and Vtnesses: cause it to clamp said rubber tube firmly to N. C.LOMBARD, said Valve-easing. W. H. JAMES.
